Firstly, it is difficult to see the exercises, which are contained within a small box in the middle of the screen, the rest of the screen around it being blank. My husband says it must be built for an older operating system, but this version was only supposed to have been published in 2009! My son and I have to screw our eyes up to read the tiny writing.
Secondly, as another reviewer pointed out, there are several mistakes. My son clicked on answers that were correct, but was told they were wrong (for anyone who speaks German, as an example they said the right answer for the translation of "I have just been to Austria" was "Ich bin Österreicher"!)
However, having said that, this CD rom is good value for money if you pay less than £6 for it as I did. There are hundreds of exercises and it is more compelling than looking through school books! Good for revision.
